Abstract

The Temperature-jump/FTIR (T-jump/FTIR) spectroscopy was introduced to resolve the decomposition kinetics parameters of [Cd(CHZ)₃](ClO ₄)₂ (CdCP) at high temperature following very rapid heating process. The increase in the absorbances during the flash pyrolysis of CdCP yielded the kinetics parameters in the range of 360-430°C at 0.1 MPa Ar atmosphere: E_a = 28.6 kJ/mol and ln A = 17. The kinetics parameters of the exothermic decomposition reaction were also determined by using DSC method. The value of E_a determined by T-jump/FITR spectroscopy is smaller than that by Kissinger method and Ozawa-Doyle method, which makes these values qualitatively consistent with other energetic materials. The T-jump/FITR spectroscopy might be resembled as the surface of explosion reaction very closely. In addition, the decomposition kinetics of evolution of the major four individual gas products was also resolved by T-jump/FITR spectroscopy, which might be essential for detailed combustion modeling of solid energetic materials.
